Abstract

PURPOSE:To prolong the life of tool and enhance the finishing accuracy by supporting part of the broaching edges for finish machining on a broaching edge rest, and mounting this broaching edge rest on the tool body through a wedge with adjustability for the height. CONSTITUTION:Broaching edges 14d, 14e, 14f for finish machining are supported on broaching edge rests 39d, 39e, 39f, which are fixed to the tool body 38 with screws 40. These rests 39d-39f are put in contact with a locating block 41 and located in specified positions. The edge tip heights of those broaching edges 14e, 14f for relief part finishing and surface finishing which wear greatly are adjusted by pinching slidable wedges 42e, 42f between the respective rests 39e, 39f and the body 38. Accordingly replacement of the broaching edges 14 is not needed because of mounting error or wear of edges, and the height adjustment reduces shocks, so that the life of the tool is prolonged and the accuracy enhanced.
